I like mine with hot dogs too, if it's the Kraft, or any kind of boxed mac a cheese.
When I make my own, however, I put bread crumbs on top. Orrr. i will cook some ground beef, cook the noddles in a tomato sauce and water mixture, and then combine afterwards with cheese. Very good. And very good to use some some of that leftover spaghetti sauce you might have. Works just as well as tomato sauce.
